Abstract

The competitive adsorption of pyridine with citrate present on Carey Lea silver sols has been observed by surface-enhanced Raman scattering. A strong influence of Cl- on this competitive adsorption is seen. The use of polyvinylpyrrolidone to stabilize colloidal aggregates is reported and competitive adsorption in this system is compared to that in nonstabilized sols. © 1985 American Chemical Society.
